When I was looking up a lot of Myers-Briggs information, I found this test to tell you which Harry Potter character you are, and which Myers-Briggs type goes with that character. Some worked well (Snape as an INTJ), but many didn't so I didn't bother to mention it on my blog.*
Bub and Pie has written her own post on Myers-Briggs types for Harry Potter characters, and her categories work much better. She doesn't break them down into all sixteen categories, instead, she sorts them into four broader categories: SF, SJ, NT, and NF.
...The Harry Potter series is all about the SJs and SPs, concrete thinkers who either follow the rules (SJ) or break them (SP). On the whole, Rowling seems to side with the SPs. Everything in the wizarding world is concrete, even the magic (especially the magic). Wizards don’t read novels – or write them. At best they read the occasional fairy tale, but Beedle the Bard appears to be the only wizard who ever had a literary imagination. Wizards are scientists: they combine ingredients to create potions, they care for magical plants and creatures, and they utter set incantations to create particular effects. There is some innovation in the wizarding world (particularly by the Half-Blood Prince), but little true creativity. Perhaps if we’d ever followed Hermione to Arithmancy class or hung out in the Ravenclaw common room we might have met a few NTs, but NF idealists are terribly thin on the ground
NT students are hard to find a Hogwarts: in the Muggle world they’re easily located by their D&D clubs, their gaming conventions, and their science fair projects. There seem to be no nerds at Hogwarts, no cliques of misfits who bond over their arcane interests. Neville’s flair for Herbology suggests an NT nature – he may be a mild-mannered INTJ, intimidated by his robust ESTJ grandmother but never quite conforming to social expectations.
I talso enjoyed this consideration of Snape and Dumbledore:
The best NTs in the Potterverse, of course, are Albus Dumbledore and Severus Snape. (Snape’s loyal following, especially in the N-dominated blogosphere, may arise from the fact that he is one of the few abstract thinkers in the concrete world of witchcraft and wizardry.) Snape is a true scientist: as the Half-Blood Prince, he tinkered with potions and created spells of his own invention. The only wizard who surpasses him for intellect and creativity is Dumbledore. His early friendship with Grindelwald – based on a shared intellectual vision – suggests to me that he is a classic NT, probably an ENTP or an INTP. Dumbledore’s quirky sense of humour, his flair for nonsense, and his unsurpassed magical knowledge all place him in the same category as Lewis Carroll, Albert Einstein, and Jon Stewart.
Whenever I've taken any Myers-Briggs-type tests, I've always been in between INTJ and INFJ. However, a recent conversation thoroughly convinced me that I'm really an INFJ. For me, INTJ is a vacation, but not where I live. As Bub and Pie says about the Potterverse, "...NF idealists are terribly thin on the ground." She does find a very few:
Perhaps the only NF in the series is Lily Potter. Against the advice of her friends, she remains loyal to Snape even though he’s an outsider and a Slytherin. She is impervious to peer pressure but not to her own ideals: when Snape goes over to the Death Eaters, she ends the friendship. Lily is described by Slughorn as an intuitive potion-maker, someone with good instincts and an ability to follow them. She harnesses the power of love so skillfully that she helps defeat the greatest wizard in the world; she also has a weak spot for a good-looking Quidditch player whose arrogance cannot conceal his romantic interest. She is credulous and even, at times, naïve: she considers Wormtail a safe repository for secrets and laughs away the suggestion that Dumbledore might ever have been friends with Grindelwald.
The only other potential NF I can think of is Remus Lupin: his life is one of tortured emotion – he is an outcast who falls in love, considers abandoning his child out of a misguided sense of duty, and ultimately gives his life for a good cause. R.I.P., Remus. We hardly knew ye.
One of the comments also adds Hagrid as a possible NF - which I can see.**
If you enjoy Myers-Briggs or Harry Potter, I highly recommend reading all of her post (click here).
* INTP's don't like being Voldemort.
** Another comment says, "Wow. This is better than how Gilligan's Island represents Dante's levels of hell!" I Googled that, but never found a Gilligan/Dante connection. I did find a webpage describing how the characters in Gilligan's Island personify the seven deadly sins (about halfway down the page):
According to the book Inside Gilligan's Island by Sherwood Schwartz (St. Martin's Press, 1994), the creator of the show confesses that he purposely patterned the 'seven stranded castaways' after the seven deadly sins. He confesses that he didn't tell anyone until years after the show was over, because he thought that people would ridicule him for attributing such a serious theme to such a silly show:
Mr. Howell (the millionaire) - greed
The Professor - pride
Mrs. Lovey Howell - thoughtless excess (gluttony)
Gilligan - sloth
Ginger (the movie star) - extravagance (later lust)
The Skipper - anger (wrath)
Mary Ann - envy
